Machinery for dressing warps



UNITED STATES SAMUEL CAMPBELL, OF WHITESTOWN, NE

NORTHBRIDGE,

MACHINERY FOR Specification of Letters Patent No To all whom it may concern:

Be it known that I, SAMUEL CAMPBELL, of WVhitestown, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Machines for Dressing VVarpYarns; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, in which drawings Figure 1, is a plan of a dresser section frame, with my improvements attached, (ties, t, out). Fig. 2, is an elevation of the same.

The common method of dressing yarns is imperfect from the abrupt manner in which the brushes come in contact with and leave the yarn, and also because it leaves one side unfinished. For dressing very fine yarns, I am aware that brushes have been placed above and below the sections; but they have been made to come in contact with and leave the yarn simultaneously; thereby causing bunches of sizing to be left upon the yarns.

Heretofore the best dressed warps have been finished by hand; the operator holding one brush over, and another beneath the yarns; and alternately putting the right and left hands forward, and brushing toward the size rolls, being careful to bring the brushes gradually into contact with the yarns, and withdraw them so as to avoid leaving bunches of sizing upon them. To imitate this motion of the skillful operator by hand; and to make the dressing machine compact, and convenient is the object of my present invention which consists in the combination of the parts, H, L, L, G, M, M M, M, G, K K K K Q, D, E, F and N, to produce the desired effect.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction, and operation.

A (Figs. 1 and 2) are the sides of a section frame secured together by ties in the usual way.

B, are the sizing rolls, D the rocker shaft having bearings at, OZ, (Z. The arms, E, are firmly secured to the shaft, D, and serve for bearings for the tubular shaft or sleeve F. The lever, G, is also secured to the rocker shaft, D.

DRESSING WARPS.

H, is a shaft which is driven by a pulley, or any other convenient way; and has two opposite cranks for operating the brush levers, M, M M, M, through the connecting rods, L and L, and one crank for operating the lever, G, through the connecting rod, G. The brush lever, M, is secured to the sleeve, F, outside the bearing arm, E, and the brush arm is secured to it at, m,- another lever, M, similar to, M, excepting there is no connecting rod, L, attached to it, is secured to the sleeve, F, outside the other bearing arm, E; and is placed in a position corresponding to, M, to operate the other end of the brush. On the shaft, N, which runs through the sleeve, F, are arms similar to, M, and M. They are keyed, or otherwise secured to shaft, N, and are represented at, M, and M. The blue lines represent the positions of the yarns and the section beams. 1

Operation: IVhen the shaft, H, is revolved in the direction indicated by the arrow, the crank, it, through rod, L, and lever, M, pushes the brush in the brush arms, K away from the size rolls, and draws the brush in arms K toward them. It drives brushes in, K toward the rolls and those in, K, away from them. It will be perceived that the brushes in, K and K are in contact with the yarns, and approaching the size rolls, and the brushes in K and K are away from the yarn, and receding from them. This is accomplished by means of the forms given to the brush arms K K K K the levers M, M M M and rocking motion of the shaft, G, operated as before explained. The brush arms move, and tilt over rollers Q.

Having described the construction and operation of my invention, what I claim and desire to secure by Letters Patent is The method of dressing warps by means of brushes above and below each section of yarn; said brushes being alternate in their movement, and constructed to come in contact with, and leave the yarn gradually by the mechanism herein described, or any other substantially the same.
